This is an under trunk LED accent. This is made by Kuryakyn and is designed to mount under the rear corners of the trunk on top of the saddlebags. Not only does this LED accent fill the void between the tour trunk & saddlebags with a flash of chrome, it also provides additional run & turn signal accent lighting to make sure that you are seen on the road. This plug & play system attaches very easily with double-sided tape and it will fit all Goldwing GL1800's from 2012-2017 except F6B. These will also NOT fit the 2001-2010 models. The rearaccessory harness K3230 is required forplug-&-play installation.3231
